Robot speeds up toxic chemical testing

The new robot that is employed by EPA is really speeding up things at the lab for testing the toxicity of chemicals. While a person can do 10-20 testing a year, the robot is able to test 10000 chemical in a week, says Robert Kavlock, the Director of the National Center for Computation and Toxicology at the U.S. Environmental Protection Agency. The goal of the project is to have a database of toxic and harmful chemicals. The use of the robot also eliminates the need for using animals in the experiments. Once the testing of a chemical is finished, the robot sends the results to scientists, who evaulate the outcome.  The costs are also drastically reduced, from millions of dollars, to thousands, Kavlock says.
